Several blog rolls on a single WordPress site using categories

Here’s a simple code example of how you can have separate blog roll areas on your WordPress website which show different types of blog content. Just add this query to your template file:

<?php
  $query = new WP_Query(array('category_name' => 'reviews'));
  
  if ($query->have_posts()): while ($query->have_posts()): $query->the_post();
?>

<div class="review">
  <h1><?php the_title(); ?></h1>
  <?php the_content(); ?>
</div>

<?php
  endwhile;
  else:
    echo 'No posts';
  endif;
?>

If you don’t want to hard code the blog roll in a template file, another option would be to add the category rolls to your menu in the menu editor. That way clicking on such a menu link will take you to the blog post list (archive) of the posts that belong to that archive.

How to allow a specific app on your child’s device using Google Family Link

I have set the app age restriction on my child’s device to PEGI 3 to make sure only the most child friendly content is available. There is one exception though, my child really loves Sim City Build It which is PEGI 7 and I was okay with making an exception for that specific game.

How to actually accomplish a special exception to the general age restriction rule was not so obvious however. I thought that I could just login with the parental access code and override the limits as the parent, but Play store was still complaining about Sim City being limited by the age restriction.

The only solution I eventually found for this problem was to login to Family Link on my own device (or alternatively just using the internet browser on a desktop computer) and then temporarily change the age restriction to PEGI 7. This can be done under controls –> content restrictions –> Google Play.

After that I was able to install the app, then immediately set the age restriction back to PEGI 3. The app is still working even after dropping the age restriction back to 3, so this ended up solving the issue.

CSS-only 3D fly-in animation

Have you ever wondered how to create a 3D-transition in which an element should fly past the camera onto the webpage? Here’s how you can do that using CSS-transforms:

See the effect in action here:

FLY IN!

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">

    <style>
        body{
            perspective: 300px; /* the smaller, the stronger sense of perspective (like short focal lenght) */
            min-height: 95vh;
            display: grid;
            grid-template-columns: 1fr 1fr 1fr;
            grid-template-rows: 1fr 1fr 1fr;
            text-align: center;

        }

        h1{
            grid-column: 2/3; /* Just for putting the h1 to center of grid */
            grid-row: 2/3; /* Just for putting the h1 to center of grid */
            transform: translate3d(800px, 200px, 1500px); /* Set the start position for the element */
            animation: myflyin 2s; /* Activate the animation called myflyin */
            animation-fill-mode: forwards; /* Keep the position from the last keyfframe */
            
        }

        @keyframes myflyin { /* Define the keyframes */

            from {
                transform: translate3d(800px, 200px, 1500px); /* Starting position */
            }

            to {
                transform: translate3d(0, 0, 0); /* End position */
            }
        }

Force refresh on Brave mobile

 Have you ever needed to force refresh a website with the Brave browser on a mobile device like iPhone or Android phone?

The need to do that may arise, for example, when developing websites for WordPress, because WordPress will attempt to cache the CSS files and your latest changes might not be reflected even if you reload the page.

Many websites advice you to go to the browser cache settings and clear the entire cache. But that is an overkill -there is a better and simpler way:

The easiest way to force Brave to force refresh on your mobile device is to switch the browser to desktop mode from the menu with the three dots. The feature is called “Request desktop site”. After switching to that, you can then switch back to a regular mobile page and the cache should be updated.

It’s as simple as that!

If even that is not working, there is a couple of other things you can attempt:

  1. Click on the slider icon right to the address bar and delete the cookies and data for that particular site
  2. Open the site in a private incognito tab
  3. Use a cache busting method like embedding a query string with a changing version number after the resource name.

How to fix the “Could not read source map for file” error when trying to setup Tensorflow.js

If you are getting a “Could not read source map for file” error in the console when trying to link to a JavaScript library like Tensorflow, the solution is simple. You propably don’t need the source map anyways unless you are planning to really digging into the code base of the library. So simply:

  1. Open the script file in your code editor
  2. Scroll all the way down
  3. Remove the source map link at the bottom of the file
